The magnitude of the z-value is used to indicate the azimuth zaimuth of the terminal, i.e. the angle of rotation around the z-axis.
The value of x is used to indicate the pitch angle pitch of the terminal, i.e. the angle of rotation around the x-axis, which is in the range of-180, 180. The value x is in positive correlation with the pitch angle, namely the larger the value x is, the larger the pitch angle is. The sign of the x value is used to indicate the orientation of the pitch angle. And when the value of x is a positive number, the terminal is indicated to tilt upwards, and when the value of x is a negative number, the terminal is indicated to tilt downwards.
The magnitude of the y value is used for indicating a roll angle roll of the mobile terminal, namely, an angle of rotation around the y axis, and the roll angle has a value range of [ -90, 90 ].

The display screen of the terminal comprises a first short edge, a first long edge, a second short edge and a second long edge which are connected end to end clockwise, and the preset direction comprises a direction of the first long edge pointing to the display interface from the center of the display screen.
It should be noted that, the collection process of the historical motion data may refer to the relevant details of the real-time motion data in an analogy manner, and details are not described herein again.
The terminal acquires a plurality of historical motion data, and the method comprises the following steps: obtaining a plurality of historical motion data in a threshold dynamic adjustment database.
Optionally, when the total amount of the historical motion data in the threshold dynamic adjustment database reaches n times of the first specified threshold, a fuzzy algorithm is used to perform data error correction on the historical motion data. Wherein n is a positive integer.
Optionally, a threshold dynamic adjustment database is stored in the terminal, and the threshold dynamic adjustment database is used for storing historical motion data.
Optionally, the historical movement data is stored in the threshold dynamic adjustment database each time the terminal determines the historical movement data. Or, every time the terminal determines i pieces of historical motion data, the i pieces of historical motion data are stored in the threshold dynamic adjustment database.
When the total amount of the historical motion data in the threshold dynamic adjustment database reaches n times of the first designated threshold, the data accuracy of the historical motion data of the first designated threshold which is used for indicating the n times of the threshold dynamic adjustment database is poor, and data error correction is needed.
Illustratively, the data error correction of the multiple historical motion data in the threshold dynamic adjustment database by the terminal by using a fuzzy algorithm includes: the terminal adopts a fuzzy algorithm to obtain the central values of a plurality of historical motion data, obtains error data of which the absolute value of the difference value with the central value is greater than the difference threshold value in the plurality of historical motion data, and deletes the error data in the threshold value dynamic adjustment database.
Optionally, in order to avoid that the data excessively occupies system resources of the terminal, when the total amount of the historical motion data in the threshold dynamic adjustment database reaches k times of the first specified threshold, the sample collection function is stopped. Wherein k is a positive integer greater than n.
It should be noted that, in the embodiment of the present application, the values of the first specified threshold, i, n, and k are not limited. For example, the value of i is 5, the first specified threshold is 200, n is a positive integer less than 10, and k is 10.
Optionally, the terminal determines the threshold correction value according to a plurality of historical motion data, including but not limited to the following possible implementation manners.
In one possible implementation manner, the terminal acquires a difference value between maximum motion data and minimum motion data in a plurality of historical motion data; and dividing the difference value by the total amount of the plurality of historical motion data to obtain a threshold correction value.
For example, the historical motion data acquired by the terminal includes 5 acceleration values, which are respectively "10", "8", "6", "7", and "9", the difference value between the maximum acceleration value "10" and the minimum acceleration value "6" is acquired as "4", and the difference value "4" is divided by the total number "5" to obtain the threshold correction value "0.8".
In another possible implementation manner, the terminal obtains an average value of a plurality of historical motion data. And acquiring the absolute value of the difference between the average value and a preset bright screen initial threshold value. And dividing the absolute value of the difference value by the total amount of the plurality of historical motion data to obtain a threshold correction value.
For example, the historical motion data acquired by the terminal includes 5 acceleration values, which are respectively "10", "8", "6", "7", and "9", an average value of the acquired 5 acceleration values is "6", a difference absolute value "0.5" between the acquired average value "6" and a preset bright screen initial threshold value "6.5", and the difference absolute value "0.5" is divided by the total amount "5" to obtain a threshold correction value "0.1".
And step 304, adding the threshold correction value and the bright screen initial threshold to obtain a target motion threshold.
Optionally, the terminal corrects the preset bright screen initial threshold according to the threshold correction value to obtain a target motion threshold, where the target motion threshold is the sum of the threshold correction value and the bright screen initial threshold.
The bright screen initial threshold is set by a user or a default setting of the terminal. This embodiment is not limited thereto.
For example, the initial bright-screen threshold is "6.5", and when the terminal determines the threshold correction value "0.1", the threshold correction value "0.1" is added to the initial bright-screen threshold "6.5" to obtain the target motion threshold "6.6".
Optionally, the terminal repeatedly executes the above steps 302 and 303 at predetermined time intervals, that is, the terminal re-determines the threshold correction value according to the plurality of historical motion data, and corrects the bright-screen initial threshold according to the re-determined threshold correction value.
And 305, controlling the display screen to be switched from a screen-turning-on state to a screen-turning-on state when the real-time motion data reaches the target motion threshold.
For example, the real-time motion data acquired by the terminal is an acceleration value of "7", and the acceleration value of "7" is greater than a target motion threshold of "6.6", so that the terminal controls the display screen to be switched from the screen-turning state to the screen-lighting state.
Optionally, when the real-time motion data reaches the target motion threshold and the state information of the terminal meets the screen lightening condition, the terminal controls the display screen to be switched from the screen lightening state to the screen lightening state.
The state information of the terminal comprises an inclination angle of the terminal in a preset direction and/or an environment brightness value of an environment where the terminal is located. The bright screen conditions include: the absolute value of the change value of the inclination angle in the first preset time length is larger than a preset angle threshold value, and/or the environment brightness value is increased in the second preset time length, and the increase value of the environment brightness value is larger than a preset brightness threshold value.
Optionally, the terminal calculates the inclination angle of the mobile terminal on each coordinate axis according to the three-dimensional vector acquired by the gyroscope or the acceleration sensor. Schematically, the terminal performs time integration on the angular velocity values according to the angular velocity values acquired by the gyroscope to obtain the inclination angles corresponding to the three coordinate axes.
Optionally, the terminal obtains an environment brightness value of an environment where the terminal is located, which is collected by the light sensor.
The terminal judges whether the state information of the terminal meets the screen lightening condition, and the method includes but is not limited to the following two possible implementation modes:
in a first possible implementation manner, when the inclination angle changes from the first angle value to the second angle value within a first preset time period, the terminal determines that the state information of the terminal meets the screen-on condition. And the absolute value of the difference between the second angle value and the first angle value is greater than a preset angle threshold value.
In a second possible implementation manner, when the ambient brightness value is increased from the first brightness value to the second brightness value within the first preset time period, the terminal determines that the state information of the terminal meets the screen-on condition. The second brightness value is greater than the first brightness value, and the absolute value of the difference between the second brightness value and the first brightness value, that is, the increase value of the environmental brightness value, is greater than the preset brightness threshold.
The first preset time length, the second preset time length, the preset angle threshold value or the preset brightness threshold value are set by the terminal in a default mode, or are set by the terminal in a default mode. This embodiment is not limited thereto.
It should be noted that the two possible implementation manners may be implemented separately or in combination, and this embodiment is not limited to this.
Optionally, if the terminal determines that the real-time motion data is smaller than the target motion threshold, or if the terminal determines that the state information of the terminal does not satisfy the screen-on condition, the terminal controls the display screen to keep the information screen state unchanged. And if the terminal judges that the real-time motion data reaches the target motion threshold and the state information of the terminal meets the screen lightening condition, the terminal controls the display screen to be switched from the screen lightening state.
Optionally, the above steps 302 to 304 may be alternatively implemented as the following steps: the terminal acquires historical motion data, wherein the historical motion data comprises an angular velocity value and/or an acceleration value of the terminal; acquiring motion characteristics of historical motion data and user characteristics of a target user, wherein the user characteristics of the target user are used for indicating behavior habits of the target user; and calling an individualized model of the terminal, and obtaining a target motion threshold value of the terminal according to the motion characteristics of the historical motion data and the user characteristics of the target user through the individualized model.

Illustratively, historical motion data acquired by the terminal is waveform data, and motion features are extracted from the waveform data, wherein the motion features comprise at least one feature of an average value, a root mean square, a standard deviation, a skewness of acceleration, a kurtosis coefficient and a crest factor.
Optionally, the terminal stores user characteristics of a target user, and the target user is an owner of the terminal. And the terminal acquires the stored user characteristics of the target user. The user characteristics of the target user are used to indicate the behavior habits of the target user, illustratively, the user characteristics of the target user include at least one of sleep time, exercise time, entertainment time, and office time.
The method for obtaining the target motion threshold value of the terminal through the personalized model according to the motion characteristics of the historical motion data and the user characteristics of the target user includes: and the terminal inputs the motion characteristics of the historical motion data and the user characteristics of the target user into the personalized model and outputs the motion characteristics and the user characteristics to obtain the target motion threshold of the terminal.
